BIOS will boot with a DIMM(s) checksum error (F1 to continue). I have 4 identical 1 gig G.skill sticks installed. They have been in for about four years. Anyway, before I installed the CPU, BIOS and Windows read them just fine. Now, BIOS only recognizes 2 sticks whereas Windows reads 4.00GB(2.00GB usable). I have tried re-seating them to no avail. I have checked in msconfig to see if max memory was checked. It was not. I've take out the CPU and looked for bent pins, damage. There is nothing there. I'm using a cooler master 101A and thought perhaps it was latched too tight. Removed it, placed the stock heatsink on and still just 2 showing up. But when I reinstall my Old CPU (Athlon X2 3.1 Brisbane) everything is fine. BIOS recognizes 4 sticks as does Windows. I've also cleared CMOS with no result.
Upgraded CPU: AMD Phenom II X6 1045T@2.7ghz 95 watts
RAM: 4096MB G.Skill DDR2 PC2-6400 (400mhz) (4 identical sticks)
MOBO: Foxconn A7GM-S 1.0 flashed to 799F1P15
Any ideas? I'm upgrading to 8 gigs (max this board can take) tomorrow. Just waiting for the package. I just find it curious that everything is normal once I install my old CPU.
